To a.Z.7 -w7z,0m it vnaconocrnx Be it known that I, CHRISTIAN E. MUUS, acitizen of the United States, residing'at Brooklyn, in the countyofKings and State of N w Yorlnhave invented new and useful Improvementsin Lubricating Devices for lVatches,of: which the following is aspeci--fica'tion. 'This invention relatesto lubricating devices andparticularly to one designed" for use in connection with watches or likeinsti'uments which arc'usually. enclosed ina case, and an" object of theinventi'on is to provide a devicethat'can be saturated with alubricating'and cleansingliquid or solution, which, due to the formand'co'nstruction of the device will retain a certain amount oflubricating liquid and cause same, by a process of evaporation, toimpregnate or saturate the air around the works of the watch and therebyact to automatically supply the said works with a correct quantity oflubricant that will insure the works against premature deterioration,and permit the works to perform their necessary function without unduestoppage or interruption.

A still further object of the invention is to provide a simple device ofthis character which will consist of a plurality of disks or membranesassociated so that when saturated with a lubricating solution, thesolution will be held in cellular formation between the disks ormembranes and the supply of liquid preserved or retained for arelatively long period of time.

Another object of the invention is to provide a lubricating device thatcan be conveniently arranged in an ordinary watch case and completelyenclosed thereby so that by a process of evaporation induced by naturalconditions, the works of the watch will be amply supplied withlubricant.

With the above and other objects in view which will appear as the natureof the invention is better understood, the same consists in the improvedconstruction and novel arrangement of parts which will hereinafter befully described and particularly pointed out in the claims.

In the accompanying drawing, has been illustrated, a single andpreferred form of the invention, it being, however, understood that nolimitations are necessarily made to the precise structural detailstherein exhibited, but that changes, alterations and may be resorted towhen desired.

- Figurel, is a perspective view of the-de- Figure 2, is a conventionalillustration showing a watch in section with thelubrieating devicemountedin 'thecase of the Watch.

Figure 3, is a'section through the device conventionally "illustratingthe-"method of cellular retention of the lubricant;

Th is arrangement of securing the disks togcther exposes thespacesbetween the iseveral disks at the periphery of the structure. Asstated, tissue paper is preferably employed and I find that a paperglazed upon trapping the liquid l'ubrica'ntto presentthe one'side iswell adapted to the purpose of i the invention. These disks are superimposed relatively as a result of the aforesaid mode of binding themtogether and they are adapted to be saturated or supplied with asuitable commercial lubricant or cleansing solution which will collectand be maintained in cellular formation between the respective disks.This is shown in the conventional illustration in Figure 3, of thedrawing.

By providing disks of tissue paper, either glazed on one side or onboth, a proper retention of the lubricant is provided for and inpractice, the device, when arranged within the case of a watch willeffectively function as a lubricatorfor a relatively long period oftime. It is of course reasonable to believe that the more of these disksthat are bound together, the greater the charge of lubricant carriedthereby. This, I- of.

and the like and of this collec'tion, find the aforesaid glazed papermost suitable for my purpose.

The device is arranged in a compact pack age and is adapted to be placedin a watch case as shown in Figure 2, so as to be interposed between theback of the case and the exposed Works of the watch. By enclosing thedevice in the case, the atmospheric air in circulation around the worksis saturated or impregnated by the natural process of evaporation and inconsequence thereof,

the works of the watch are, for all intents and purposes, constantlybathedin this vaporized air. Care should be exercised in the selectionof a proper kind oflubricating .liquid so that undue charges of gum orforeign substances will not be carried into the active operating partsof the Watch works. There are inany standard or Well known lubricatingsolutions that can be used for this purpose. When the device is arrangedbetween the back or cover section of the watch oase, and the open side Yof the watch works, the joint between the said back of the case and 'thefront part thereof is sealed 'to an appreciable extent and foreignparticles arrested by the de vice as will be understood.

" I have found that by mixing fifty 'per cent lubricating oil with fiftyper cent kerosene, the device acts both'as a cleanser and as alubrlcator.

I do not wish tobe limited in this respect, however, as other Well knownsolutions can be empl'oyed in 2. As a new article of manufacture, a

lubricating device consisting of a plurality of tissue paperdiskssaturated in oil and secured together centrally thereof to spac thedisks at their peripheries.

3. As a new article of manufacture, a 7

watch lubricator comprising a plurality of identically formed diskssecured together centrally thereof to space the disks at theirperipheries designed to fit withina watch case and saturated withaliquid: lubri'cat ing-solution so that charges of the solution willbeheld in cellular formation between the disks subject to being-cast offby the natural process of evaporation;

In testimony whereof I have affixed my signature.
